use deforming object as particle fluid object

[Tiago]

Hello,

Is is possible to transform a deformed/animated object (bgeo sequence) into a particle fluid object?

I only see the use object transform toggle, and the particles don't seem to follow the animated bgeo sequence.

Thanks in advance,

When you emit fluid in to a simulation, the simulation takes over. You need to drive the particle fluid with the original point cloud inside the simulation. I think that is your question...

Several ways to do this. You can drive the position of the points implicitly with a Position POP in the pop network build for you by the FLIP Fluid tool but it sure won't look like fluid as you are completely taking over. Note that the Position POP does not update velocity (nor should it).

You can use Attractor POP, Attribute Transfer POP or Point Clouds which work quite well in DOPs to impart either accelerations or velocities on to your fluid from the originating point cloud. This will keep the fluid look around in the simulation.

A third way is to use Forces in DOPs. The Field Force DOP allows you to reference any geometry and use any attribute on that geometry as a direct force or an angular force. The attached file uses this method.

Thank you very much for your answer Jeff.

It (and the hip file) was much more than I hoped for.

Kind regards,
